Lync Mobile 2013 – Does not play voicemails

The other day I found this little issue in a deployment

We enabled UM for pilot users, and everything worked fine. But when we tried to play voicemails from an iPhone, it did not play the message. We tried with Android Phone and same error.



We executed the following cmdlet to change the audio codec to MP3.

Set-UMDialPlan -Identity MyUMDialPlan -AudioCodec MP3

With this change, both devices could play voicemails

Lync 2013 – Automatic Login process

Hi all,

I reviewed the automatic login process in Lync 2013,and  I found that the first steps are different than Lync 2010.

In Lync 2010 the login process was the follow:

  • _sipinternaltls._tcp.<sip domain>
  • _sip._tls.<sip domain>
  • sipinternal.<sip domain>
  • sip.<sip domain>
  • sipexternal.<sip domain>

I put a Wireshark trace on my Lab with Lync 2013

Note: I did not create any DNS register, because I wanted trace the full process.


1) DNS A Register : lyncdiscoverinternal.<sip domain>

This DNS A Register was included since Lync 2010 CU4 to offer Lync Mobile Service. Now with Lync 2013, it’s the first option to automatic login.

2) DNS A Register: lyncdiscover.<sip domain>

As previous register, added to Lync since Lync 2010 CU4, but with different porpouse. This DNS register, allow user outside corporative LAN, to connect to Lync Mobile Clients, the previous one only works for internal users.

Imagen 025

3) DNS SRV: _sipinternaltls._tcp.<sip domain>

From here, are same steps as Lync 2010

4) DNS SRV: _sip._tls.<sip domain>

Imagen 027

5) DNS A: sipinternal.<sip domain>

Imagen 028

6) DNS A: sip.<sip domain>

7) DNS A: sipexternal.<sip domain>

Note: Lync Windows Store, stops in the second step

Audiocodes FXO – Does not release call


We have an Audiocodes Mediant 1000B Gateway integrated with Lync Server 2013, and it has a card with 4 FXO ports

When we receive an incoming call from the PSTN, we can answer without problem. The issue comes when the call is finished. If the call is terminated from Lync side, the call FXO port is released. But, if the PSTN side is who end the call, the call does not release and we can see the FXO port busy.


We are in Mexico, so we change Call Progress Tone File with other one made for Mexico (Default file is for USA ). Once we did it, we tried again and the problem was solved. No matter who end the call, the FXO port was released.
